摘      要：Local hydrodynamics of a gas–liquid–solid system,such as bubble circulation regime,gas holdup,liquid velocity and axial profile of solid concentration,are studied in a two-stage internal loop airlift *** correlations for gas holdup and liquid velocity are proposed to ease the reactor design and *** bubble circulation regimes were displayed in the first(lower) and second(upper) *** superficial gas velocity and solid loading can promote regime transition of the second stage,and the gas holdup of the second stage is higher than that of the lower *** addition,the effects of solid loading on bubble behaviour are experimentally investigated for each *** is found that bubble size in the downcomer decreases with the presence of solid particles,and bubble size distribution widens under higher superficial gas velocity and lower solid loading.
